BACKGROUND

Aspects of the present disclosure relate generally to wirelesscommunication systems, and more particularly, to beam sweep basedsemi-persistent scheduling and/or configured grant activation.

Wireless communication systems are widely deployed to provide varioustypes of communication content such as voice, video, packet data,messaging, broadcast, and so on. These systems may be multiple-accesssystems capable of supporting communication with multiple users bysharing the available system resources (e.g., time, frequency, andpower). Examples of such multiple-access systems include code-divisionmultiple access (CDMA) systems, time-division multiple access (TDMA)systems, frequency-division multiple access (FDMA) systems, andorthogonal frequency-division multiple access (OFDMA) systems, andsingle-carrier frequency division multiple access (SC-FDMA) systems.

These multiple access technologies have been adopted in varioustelecommunication standards to provide a common protocol that enablesdifferent wireless devices to communicate on a municipal, national,regional, and even global level. For example, a fifth generation (5G)wireless communications technology (which can be referred to as 5G newradio (5G NR)) is envisaged to expand and support diverse usagescenarios and applications with respect to current mobile networkgenerations. In an aspect, 5G communications technology can include:enhanced mobile broadband addressing human-centric use cases for accessto multimedia content, services and data; ultra-reliable-low latencycommunications (URLLC) with certain specifications for latency andreliability; and massive machine type communications, which can allow avery large number of connected devices and transmission of a relativelylow volume of non-delay-sensitive information.

For example, for various communications technology such as, but notlimited to NR, increases in bandwidth may result in implementationcomplexities with regard to transmission of data during certain modes.Thus, improvements in wireless communication operations may be desired.

DETAILED DESCRIPTION

Various aspects are now described with reference to the drawings. In thefollowing description, for purposes of explanation, numerous specificdetails are set forth in order to provide a thorough understanding ofone or more aspects. It may be evident, however, that such aspect(s) maybe practiced without these specific details.

The described features generally relate to beam sweep basedsemi-persistent scheduling and/or configured grant activation in newradio (NR). Specifically, NR supports very high data rates with lowerlatency. As the NR band uses high frequencies for communication,propagation loss and other channel losses may be experienced. Tocompensate for the losses, directional communication may be useful atsuch frequencies. Antenna arrays with large number of antenna elementsmay enable such communication due to smaller wavelengths, providingbeamforming gain to the radio frequency link budget which may help incompensation for propagation losses. To transmit on multiple directionalbeams, accurate alignment of transmitted and received beams may beimplemented. In order to achieve alignment of beam pairs and to have endto end performance with desired delay, beam management operations may beperformed in NR. For example, one such beam management operation may bebeam sweeping, which refers to covering a spatial area with a set ofbeams transmitted and received according to pre-specified intervals anddirections.

In some implementations, on the downlink, beam sweeping may correspondto an exhaustive search based on synchronization signal (SS) blocksreceived by UE. On the uplink, beam sweeping may be based on a soundingreference signal (SRS) transmitted by UE and received by the networkentity (gNB). However, beam sweeping may not be performed during or forsome types of signaling. In particular, beam sweeping may not besupported in semi-persistent scheduling (SPS) and/or configured grant(CG) activations. Instead, a single active beam may be used per grantfor physical downlink shared channel (PDSCH) and/or physical uplinkshared channel (PUSCH) transmission after activation. Hence, it would bedesirable to implement beam sweeping in SPS and/or CG activations orreconfigurations (e.g., via downlink control information (DCI)) toimprove robustness of communication on one or both the uplink anddownlink. Implementing beam sweeping during such signaling may bedesirable when a retransmission cycle is not long enough for anyretransmissions (e.g. 0.5 ms). Specifically, a beam sweep pattern may bedynamically indicated in an activation DCI and may be multiplexed in atime domain (e.g., slot based or mini-slot based), in a frequencydomain, or spatial domain.

In one implementation, a network entity may determine a beam sweeppattern for at least one of a SPS based downlink periodic transmission,an uplink control transmission for the SPS based downlink periodictransmission, or a CG based uplink periodic transmission. The networkentity may also transmit an indication including the beam sweep patternto a UE. In another implementation, a UE may receive a beam sweeppattern for at least one of a SPS based downlink periodic transmission,an uplink control transmission for the SPS based downlink periodictransmission, or a CG based uplink periodic transmission from a networkentity. The UE may configure communication using two or more beams on atleast one of an uplink channel or downlink channel based on the beamsweep pattern. The UE may further communicate data according to the beamsweep pattern on at least one of the uplink channel or the downlinkchannel.

The described features will be presented in more detail below withreference to FIGS. 1-10.

As used in this application, the terms “component,” “module,” “system”and the like are intended to include a computer-related entity, such asbut not limited to hardware, software, a combination of hardware andsoftware, or software in execution. For example, a component may be, butis not limited to being, a process running on a processor, a processor,an object, an executable, a thread of execution, a program, and/or acomputer. By way of illustration, both an application running on acomputing device and the computing device can be a component. One ormore components can reside within a process and/or thread of executionand a component can be localized on one computer and/or distributedbetween two or more computers. In addition, these components can executefrom various computer readable media having various data structuresstored thereon. The components can communicate by way of local and/orremote processes such as in accordance with a signal having one or moredata packets, such as data from one component interacting with anothercomponent in a local system, distributed system, and/or across a networksuch as the Internet with other systems by way of the signal. Softwareshall be construed broadly to mean instructions, instruction sets, code,code segments, program code, programs, subprograms, software modules,applications, software applications, software packages, routines,subroutines, objects, executables, threads of execution, procedures,functions, etc., whether referred to as software, firmware, middleware,microcode, hardware description language, or otherwise.

Techniques described herein may be used for various wirelesscommunication systems such as CDMA, TDMA, FDMA, OFDMA, SC-FDMA, andother systems. The terms “system” and “network” may often be usedinterchangeably. A CDMA system may implement a radio technology such asCDMA2000, Universal Terrestrial Radio Access (UTRA), etc. CDMA2000covers IS-2000, IS-95, and IS-856 standards. IS-2000 Releases 0 and Aare commonly referred to as CDMA2000 1×, 1×, etc. IS-856 (TIA-856) iscommonly referred to as CDMA2000 1×EV-DO, High Rate Packet Data (HRPD),etc. UTRA includes Wideband CDMA (WCDMA) and other variants of CDMA.

The techniques described herein may be used for thesystems and radio technologies mentioned above as well as other systemsand radio technologies, including cellular (e.g., LTE) communicationsover a shared radio frequency spectrum band. The description below,however, describes an LTE/LTE-A system for purposes of example, and LTEterminology is used in much of the description below, although thetechniques are applicable beyond LTE/LTE-A applications (e.g., to fifthgeneration (5G) new radio (NR) networks or other next generationcommunication systems).

The following description provides examples, and is not limiting of thescope, applicability, or examples set forth in the claims. Changes maybe made in the function and arrangement of elements discussed withoutdeparting from the scope of the disclosure. Various examples may omit,substitute, or add various procedures or components as appropriate.

FIG. 1 is a diagram illustrating an example of a wireless communicationssystem and an access network 100. The wireless communications system(also referred to as a wireless wide area network (WWAN)) can includebase stations 102, UEs 104, an Evolved Packet Core (EPC) 160, and/or a5G Core (5GC) 190. The base stations 102 may include macro cells (highpower cellular base station) and/or small cells (low power cellular basestation). The macro cells can include base stations. The small cells caninclude femtocells, picocells, and microcells. In an example, the basestations 102 may also include gNBs 180, as described further herein. Inone example, some nodes of the wireless communication system may have amodem 240 and communicating component 242 for determining configuringcommunication based on a beam sweep pattern received from the basestation 102/gNB 180, as described herein. In addition, some nodes mayhave a modem 340 and configuring component 342 for determining a beamsweep pattern for SPS and/or CG activations, as described herein. Thougha UE 104 is shown as having the modem 240 and communicating component242 and a base station 102/gNB 180 is shown as having the modem 340 andconfiguring component 342, this is one illustrative example, andsubstantially any node or type of node may include a modem 240 andcommunicating component 242 and/or a modem 340 and configuring component342 for providing corresponding functionalities described herein.

The base stations 102 configured for 4G LTE (which can collectively bereferred to as Evolved Universal Mobile Telecommunications System (UMTS)Terrestrial Radio Access Network (E-UTRAN)) may interface with the EPC160 through backhaul links 132 (e.g., using an S1 interface). The basestations 102 configured for 5G NR (which can collectively be referred toas Next Generation RAN (NG-RAN)) may interface with 5GC 190 throughbackhaul links 184. In addition to other functions, the base stations102 may perform one or more of the following functions: transfer of userdata, radio channel ciphering and deciphering, integrity protection,header compression, mobility control functions (e.g., handover, dualconnectivity), inter-cell interference coordination, connection setupand release, load balancing, distribution for non-access stratum (NAS)messages, NAS node selection, synchronization, radio access network(RAN) sharing, multimedia broadcast multicast service (MBMS), subscriberand equipment trace, RAN information management (RIM), paging,positioning, and delivery of warning messages. The base stations 102 maycommunicate directly or indirectly (e.g., through the EPC 160 or 5GC190) with each other over backhaul links 134 (e.g., using an X2interface). The backhaul links 134 may be wired or wireless.

The base stations 102 may wirelessly communicate with one or more UEs104. Each of the base stations 102 may provide communication coveragefor a respective geographic coverage area 110. There may be overlappinggeographic coverage areas 110. For example, the small cell 102′ may havea coverage area 110′ that overlaps the coverage area 110 of one or moremacro base stations 102. A network that includes both small cell andmacro cells may be referred to as a heterogeneous network. Aheterogeneous network may also include Home Evolved Node Bs (eNBs)(HeNBs), which may provide service to a restricted group, which can bereferred to as a closed subscriber group (CSG). The communication links120 between the base stations 102 and the UEs 104 may include uplink(UL) (also referred to as reverse link) transmissions from a UE 104 to abase station 102 and/or downlink (DL) (also referred to as forward link)transmissions from a base station 102 to a UE 104. The communicationlinks 120 may use multiple-input and multiple-output (MIMO) antennatechnology, including spatial multiplexing, beamforming, and/or transmitdiversity. The communication links may be through one or more carriers.The base stations 102/UEs 104 may use spectrum up to Y MHz (e.g., 5, 10,15, 20, 100, 400, etc. MHz) bandwidth per carrier allocated in a carrieraggregation of up to a total of Yx MHz (e.g., for x component carriers)used for transmission in the DL and/or the UL direction. The carriersmay or may not be adjacent to each other. Allocation of carriers may beasymmetric with respect to DL and UL (e.g., more or less carriers may beallocated for DL than for UL). The component carriers may include aprimary component carrier and one or more secondary component carriers.A primary component carrier may be referred to as a primary cell (PCell)and a secondary component carrier may be referred to as a secondary cell(SCell).

In another example, certain UEs 104 may communicate with each otherusing device-to-device (D2D) communication link 158. The D2Dcommunication link 158 may use the DL/UL WWAN spectrum. The D2Dcommunication link 158 may use one or more sidelink channels, such as aphysical sidelink broadcast channel (PSBCH), a physical sidelinkdiscovery channel (PSDCH), a physical sidelink shared channel (PSSCH),and a physical sidelink control channel (PSCCH). D2D communication maybe through a variety of wireless D2D communications systems, such as forexample, FlashLinQ, WiMedia, Bluetooth, ZigBee, Wi-Fi based on the IEEE802.11 standard, LTE, or NR.

The wireless communications system may further include a Wi-Fi accesspoint (AP) 150 in communication with Wi-Fi stations (STAs) 152 viacommunication links 154 in a 5 GHz unlicensed frequency spectrum. Whencommunicating in an unlicensed frequency spectrum, the STAs 152/AP 150may perform a clear channel assessment (CCA) prior to communicating inorder to determine whether the channel is available.

The small cell 102′ may operate in a licensed and/or an unlicensedfrequency spectrum. When operating in an unlicensed frequency spectrum,the small cell 102′ may employ NR and use the same 5 GHz unlicensedfrequency spectrum as used by the Wi-Fi AP 150. The small cell 102′,employing NR in an unlicensed frequency spectrum, may boost coverage toand/or increase capacity of the access network.

A base station 102, whether a small cell 102′ or a large cell (e.g.,macro base station), may include an eNB, gNodeB (gNB), or other type ofbase station. Some base stations, such as gNB 180 may operate in atraditional sub 6 GHz spectrum, in millimeter wave (mmW) frequencies,and/or near mmW frequencies in communication with the UE 104. When thegNB 180 operates in mmW or near mmW frequencies, the gNB 180 may bereferred to as an mmW base station. Extremely high frequency (EHF) ispart of the RF in the electromagnetic spectrum. EHF has a range of 30GHz to 300 GHz and a wavelength between 1 millimeter and 10 millimeters.Radio waves in the band may be referred to as a millimeter wave. NearmmW may extend down to a frequency of 3 GHz with a wavelength of 100millimeters. The super high frequency (SHF) band extends between 3 GHzand 30 GHz, also referred to as centimeter wave. Communications usingthe mmW/near mmW radio frequency band has extremely high path loss and ashort range. The mmW base station 180 may utilize beamforming 182 withthe UE 104 to compensate for the extremely high path loss and shortrange. A base station 102 referred to herein can include a gNB 180.

The IP Services 176 may include theInternet, an intranet, an IP Multimedia Subsystem (IMS), a PS StreamingService, and/or other IP services. The BM-SC 170 may provide functionsfor MBMS user service provisioning and delivery. The BM-SC 170 may serveas an entry point for content provider MBMS transmission, may be used toauthorize and initiate MBMS Bearer Services within a public land mobilenetwork (PLMN), and may be used to schedule MBMS transmissions. The MBMSGateway 168 may be used to distribute MBMS traffic to the base stations102 belonging to a Multicast Broadcast Single Frequency Network (MBSFN)area broadcasting a particular service, and may be responsible forsession management (start/stop) and for collecting eMBMS relatedcharging information.

The 5GC 190 may include a Access and Mobility Management Function (AMF)192, other AMFs 193, a Session Management Function (SMF) 194, and a UserPlane Function (UPF) 195. The AMF 192 may be in communication with aUnified Data Management (UDM) 196. The AMF 192 can be a control nodethat processes the signaling between the UEs 104 and the 5GC 190.Generally, the AMF 192 can provide QoS flow and session management. UserInternet protocol (IP) packets (e.g., from one or more UEs 104) can betransferred through the UPF 195. The UPF 195 can provide UE IP addressallocation for one or more UEs, as well as other functions. The UPF 195is connected to the IP Services 197.

Each modulator/demodulator 1154 through1155 may further process the input samples (e.g., for OFDM, etc.) toobtain received symbols. A MIMO detector 1156 may obtain receivedsymbols from the modulator/demodulators 1154 and 1155, perform MIMOdetection on the received symbols, if applicable, and provide detectedsymbols. A receive (Rx) processor 1158 may process (e.g., demodulate,deinterleave, and decode) the detected symbols, providing decoded datafor the UE 104 to a data output, and provide decoded control informationto a processor 1180, or memory 1182.

The processor 1180 may in some cases execute stored instructions toinstantiate a communicating component 242 (see e.g., FIGS. 1 and 2).

On the uplink (UL), at the UE 104, a transmit processor 1164 may receiveand process data from a data source. The transmit processor 1164 mayalso generate reference symbols for a reference signal. The symbols fromthe transmit processor 1164 may be precoded by a transmit MIMO processor1166 if applicable, further processed by the modulator/demodulators 1154and 1155 (e.g., for SC-FDMA, etc.), and be transmitted to the basestation 102 in accordance with the communication parameters receivedfrom the base station 102. At the base station 102, the UL signals fromthe UE 104 may be received by the antennas 1134 and 1135, processed bythe modulator/demodulators 1132 and 1133, detected by a MIMO detector1136 if applicable, and further processed by a receive processor 1138.The receive processor 1138 may provide decoded data to a data output andto the processor 1140 or memory 1142.

The processor 1140 may in some cases execute stored instructions toinstantiate a configuring component 342 (see e.g., FIGS. 1 and 3).

The components of the UE 104 may, individually or collectively, beimplemented with one or more ASICs adapted to perform some or all of theapplicable functions in hardware. Each of the noted modules may be ameans for performing one or more functions related to operation of theMIMO communication system 1100.
